Acoustic telemetry resources, papers, and information on how to choose transmitters for your study. Resources Depth or Temperature Telemetry Product Comparison A datasheet which shows the comparison of Sonotronics products associated with Depth and Temperature Telemetry Understanding Sonotronics Unique Pinger ID Algorithm A document which explains the algorithm used by Sonotronics for the unique ID of transmitters. Custom transmitter labels Email us to customize the labels in your transmitters. This allows you to leave a visible message that shows through the clear wall of the transmitter telling anglers, etc. where they can send the transmitters if found How to choose transmitters for your study Consider the following when choosing the appropriate transmitter. Size – The commonly used rule is 1.5% – 2% of the animal weight in air is maximum allowable transmitter weight in water . Exceptions to this rule are sometimes made by biologists in the case of robust species, crustaceans, and other animals that are determined to be able to hold a larger transmitter. Lifetime – It is recommended that a lifetime that is 125% of the actual length of the study is used. This allows extra room at the end of the study, and helps guarantee a high output from the transmitters throughout the study. Range – It is recommended that the highest output transmitter available that fits in the necessary lifetime and size categories be used. This guarantees greatest ranges in both automatic and manual tracking. Keep in mind that a number of factors in the environment can limit range. Telemetry – There are a number of telemetry options available on Sonotronics transmitters. Temperature, acceleration (used for feeding and mortality), depth, and tilt. These options are chosen based upon the data desired in the study. The Don L. Brumbaugh Memorial Equipment Scholarship The Sonotronics’ Equipment Scholarship, established in 2005, commemorates Donald L. Brumbaugh’s pioneering work in the development of fisheries and wildlife biotelemetry technologies. The scholarship is designed to aid students in fisheries research projects. Read more…

SUR SUBMERSIBLE ULTRASONIC RECEIVER Sonotronics proudly introduces this new addition to available fisheries research technologies. This rugged, inexpensive, long life unit allows for detection of fish passage within its detection area. Strings, arrays, or individual receivers can be utilized depending on the resolution of detection desired in the study. One of the main principles behind the SUR is its ability to save valuable field time, potentially reducing project costs. The SUR brings new features and options to the marketplace aiding in the continued development of fisheries research technologies. Features 1. Frequency scanning – large numbers of unique transmitters 2. Ability to detect transmitters also used in manual tracking 3. Backwards compatibility with all Sonotronics transmitters 4. Ability to determine presence of data in the SUR without retrieving the receiver – “ping and response” 5. Ability to interface with a variety of communication systems: cellular and wireless 6. Long battery life: 8 months with typical configuration 7. Saves valuable time in the field reducing manual tracking hours The SUR is simply moored using the eye bolt on the bottom. Its natural buoyancy will keep the unit upright in the water column. Transmitters within the units detection area will be logged to the on board memory along with date and time. The SUR can be interrogated remotely for the presence of data, allowing it to be left alone with no data hits. Data is then downloaded via the serial port. The SUR is a stand-alone submersed unit which allows for detection and logging of the same transmitters used in manual tracking, including any Sonotronics past or present transmitters. The SUR is a scanning receiver allowing for transmitters on different frequencies to be logged, also allowing exclusive channels for specialty transmitters. The SUR is designed to interface with a variety of communication systems allowing for greater system flexibility and reduce field time. The CUB cellular uplink buoy allows for real time cell phone communication upon animal passage. Radio uplink buoys are now available allowing for remote data download and configuration. 900MHz and 2.4GHz (internationally approved) bands are available. SURsoft Free software for communications with the SUR’s – SURsoft. SURsoft can be used to set time and date, download data, program frequency scanning maps, and many other options. SURsoft now includes a data processing module (As shown on the figure). The data processing center can be used to process and examine the data obtained from SUR’s, saving valuable time in sorting data. Features include examining data by transmitter, processing telemetry data, and viewing a graphic display of activity at an SUR. The SUR’s available ping and response transponding allows researchers to “ping down” to the SUR on a separate frequency, asking it to “ping up” its status, which can be detected with a manual tracking receiver. The SUR transmits a ping sequence related to the presence/absence of data in its flash memory. On many projects, this can save field time as the units do not need to be retrieved to determine data presence.

Acoustic Transmitters and Receivers -Sonotronics offers an array of tracking products built on the concept of an Integrated Tracking Approach – a method that permits interoperability between product types, as well as forward and backward compatibility. TRACKING PRODUCTS Sonotronics offers an array of tracking products built on the concept of an Integrated Tracking Approach – a method that permits interoperability between product types, as well as forward and backward compatibility. As an example, recently a transmitter used to tag a fish 14 years earlier was detected by a modern MANTRAK receiver, and recovered on a lake bottom by use of an Underwater Diver Receiver (UDR) used primarily for the recovery of tagged equipment. This flexibility and consistency protects your investment in equipment, and allows for collaboration between groups with different interests: many universities use Sonotronics passive tracking products for long term fisheries studies, while at the same institution, an engineering group uses equipment tracking transmitters to tag submerged electronics packages for later retrieval, and both groups use the same active tracking receivers to obtain real-time information on either fish or equipment location and associated telemetry. Although this equipment is highly compatible, there are some detailed differences that help in particular applications: for example Equipment Marking Transmitters (EMTs) the same internal electronics as passive tracking tags used in fisheries research, the EMTs are housed in rugged, brightly colored PVC, with large mounting holes allowing use of standard zip ties for easy attachment to equipment. Based on the application area, Sonotronics tacking products are divided into 3 areas: Active Tracking, Passive Tracking, and Equipment Tracking.
